Can't run the app because 'experiment is not enabled'

Hello community,

I am a very beginner in Forge and JS, trying to run my app but can’t do because of that error:

File was processed with these loaders:
 * ../tunnel/node_modules/babel-loader/lib/index.js
You may need an additional loader to handle the result of these loaders.
Error: The top-level-await experiment is not enabled (set experiments.topLevelAwait: true to enabled it)

On SO I found it’s needed to put this excerpt to webpack.config.js file

experiments: {
  topLevelAwait: true
}

However, I can’t find this file.

What to do to make the app running?

You are probably using await outside of a function scope, try adding inside it.

Remember if wait goes inside of the function, this function has to be async.
